The invention relates to a measuring and lling apparatus for dispensing` predetermined* amounts of liquid and semiliquid materials, such as, for example, oils and fats and more particularly, to means for preventing operation of the filling means in the .event 'a container fails of carriage relative to the filling spout.

One of the objects of the invention isto provide improvements in machines for dispensing predetermined amounts of liquid and semiliquid materials for the filling of packaging containers.

Another object of the invention is to provide improved means Afor preventingoperation of` a. filling means in the eventV the packaging container fails of carriage relative to the lling spout. I Y n In the drawings, like characters of reference are used to designate similar elements.

Figure 1 is a plan view of the measuring andA lling device constructed in accordance with the present invention. I

Figure 2 is a side view taken substantially on line 2-2 of Figure 3. A

Figure 3 is a sectional view taken substantially on line 3-3 of Figure 2.

Figure 4 isa view taken substantiallyronlineY 44 of Figure 2, the means for preventing operation of the filling means inthe event a packaging container fails of carriage relative to the filling spout, being omitted.

Figure 5 is an enlarged detail view, partly in section, of the filling nozzle. o

Figure 6 is an enlarged detail, partly in section. showing one side view of the means for preventing operation of the filling means in therevent a packaging container fails of carriage relative to the filling spout.

Figure 7 is another side view,partly in section, ci the means shown in Figure 6.

Figure 8 is a detail of the conveyor drive means. The device comprises platform or table top I rigidly supported upon standards 2, 3, 4 and 5,7the standards being reinforced with suitable crossmembersffor example, cross members 6, 1. 8,9, IU, II and I2.

The device as shown in the drawings utilizes two measuring and filling apparatuses. Inasmuchas both apparatuses employ identical'elements, it is deemed necessary to describe` but one in detail.

In Figure 5, filling nozzle I3 communicates through conduit I4 withlpipe line I5. Pipe line I5 is closed at its free end I6 as by threaded shackle l1 and intermediate its ends is provided with a plurality of relatively small inlet openings la. Pipeline l5 isrrecip'rocmiy mounted through,

relatively large ,r'radially spaced, annular chamber I9, the openings I8 at all times being within the limits of chamber I9.

chamber la is provided with inlet openingen and is rigidly affixed through opening 2| in table I as by integral ange 22 and threaded fitting 23. `Leakage between chamber I9 and pipe line I5 is lprevented through couplings 24 and 25. The lling material is forcibly fed Within chamber I9 but is materially reduced in pressure in its passagethrougn openingsl, so much so that spattering of the material asit issues from noz` j zleV I3 is practically nil.

Opening 20 communicatesthrough conduit 2li with four-way valve 21 which in turn communi- 4 cates through lines 28 and 29l with measuring cylinder 30 and through line 3| with a source ofrmaterial not shown, Measuring cylinder 30 is rigidly affixed as by bolts 32 to theundersurface of tableA I. VValve 21 and measuring cylinder Y 30 are of the 'conventional type and since each of these elements is well known in the art, it is'V deemed unnecessaryY to describeeither of them infurther detail. Y Y

Belt conveyor 33 travels over the upper surface of table I and immediately beneathnlling spout,V

I3 and serves to carryV filling containers. 34 relative to filling spout I3. Conveyor 33 travels over rollers 35 and 36. Roller 35 is pinioned to shaft 31, journaled within bearings 38 rigidly afdxed to standards 4 and 5. Roller 36 ispinioned to` shaft 39 journaled withinvbearings 40 rigidly secured to standards 2 and V3. comprising angles 4I are rigidly secured to table I to either side of conveyor 33. As shown in Figure 2, conveyor 33 suitably 'connects with car-' ton delivery conveyor 42 and take-away confV veyor 43.

The filling spout I3 is reciprocatedand the valve 21 through which the measuring cylinderA 30 is controlled and conveyory 33 are operated .in

As shown in Figures 2, 4and,8, cain49 pinioned `to shaft 44 and controls the'move `ment of conveyor 33 through the medium of rod 50, ratchet and pawl mechanism 5I, shaft 52'and gears 53 and 54.

ber 6, and engages cam 49 through the medium of spaced yrollers 56 mounted upon linky 51.

Suitable guides Rod 50 is slidably mounted through bearing 55 rigidly secured to cross mem- Ratchet mechanism 5| and gear 53 are pinioned to shaft 52, which shaft is journaled in bearings within keepers 55 rigidly Asecured to cross members II and |2. Collars 58 prevent longitudinal movement of rocker 83 on shaft 54. Rocker 53 connects with pipe line I5 and thus the nozzle I3, through the medium of -link 51. Nozzle I3 is reciprocated downwardly relatively to a pack-` aging container 34 following each movement of a packaging container 34 therebeneath and again upwardly following iilling of the container.

As shown in Figures 3, 6 and 7, crank arm 5| also controls the operation of valves 2,1 through th'e medium of link 68, pawl 89, ratchetwheel 10, gear wheels 1| and 12, crank arm 13 andlinks 14 and 15. Pawl 89 is spring tensioned against ratchet wheel 10 and its circumferential movement relative to ratchet wheel 101s conltrolled by arm 18,5 mounted for free movement on shaft 11, Ratchet rwheel 10 Vand gear wheel 1| are pinioned to shaft 11. Shaft 11 is journaled withinV bearings 18 rigidly secured against base plate 19.

Gear wheel 12 is driven by gear wheel 1| and to? gether with crank arm 13 is rigidly secured (to 8| also rigidly secured to base 19. Link 14 connects crank arm 13 with one of the valves 21, and

vlink 15 4connects the two valves 21, whence it is seen that both of the valves are operated simultaf neouslyfrom a common source of power. Y

Reference isv now" had to Figures 6 and 7 in which is shown in detail the means for preventing operation of valves 21 and consequently the force feed of material through nozzle I3 in the event a container'34 fails of carriage beneath one Vof the nozzles I3. It'will be seen in these figures that each of the'- cartons 34` is provided with an upln keepers I 03 rigidly secured to the undersurface of table I.

Crank arm |04 is pinioned to shaft |02 in opposed relationship with trip lever and through the medium of link |05 engages crank member |06 mounted for free movement on shaft 11. Crank member |08 is provided with flange member |01 adapted for movement circumferentially of ratchet wheel 10 and intermediate pawl 89 and ratchet wheel 10 to force pawl 89 out of engagement with ratchet wheel 10 for one complete movement. Extreme downward movement of rod 94 serves to move ange |01 intermediate pawl89. and ratch'et wheel 10.

Cam v|08 is pinioned rto drive shaft 44 and through the medium of rod |09, pusher plate ||0 and crank III, serves intermittently to withhold bell crank 90 and thus the movement of pin 88 through openings 81, from against the gravity action of rod 94 and weight 95. Rod |09 is slidably mounted rthrough bearings I I2 and I I3, and opening |I4 provided in table I.V Bearing I|2 is suitably mounted within frame support I I5 which in turn is rigidly secured to cross member |0. Bearing I|3 is rigidlysecured to one of the risers 85. Rod |09 at one end engages cam |08 through the medium of roller |||.Y Pusher plate ||0 is rigidly secured adjacent the opposite end of rod |09 andis adapted to engage crank arm I|| which in turn is pinioned to shaft 92.

Each movement of conveyor 33 normally delivers Va new container 34 beneath nozzle I3 and simultaneously with each movement of the conveyor 33, cam- I 08'moves rod |09 to the extreme v35 shaft 80. Shaft 80 is journaled within bearings standing cover portion 82 adapted for passage between spaced guide members 83 and 84. YGuide members 83V and 84 are rigidly mounted opposite nozzle I3 adjacent one side edge of conveyor 33 and in longitudinal alignment with conveyor 33 and at their entrance end 85 are provided with outwardly ared lipsy to assure positive reception of cover portion 82 therebetween. Guide'- members 83 and 84 are rigidly mounted on risers 85 which in turn are rigidly secured to table I. Guides 83 and 84 are provided with corresponding openings V81'for the free passage therethrough of pin 88 inthe absence of a cover portion 82 therebetween. Pin 88 m rigidly secured to arm 89 of bell crank 90 pinioned as at 3| on shaft 92.

Shaft 92 is rotatably mounted'within suitable keepers 93 which in turn are rigidly Ysecured through risers 88. VRod 94 provided with integral. weight member 85 is pinioned at one end as at 98 to arm 91 of bellcrank 90 and adjacent its opposite end as atl 98 is slidably mounted :through a suitable opening provided in table I. Rod 94, at its'free end 99 andthrough the medium of adjustment bolt |00, contactably engages trip lever |0I, rigidly secured to shaft |02.` .Shaft |02 is journaled within suitable bearings provided withof its uppermost movement whence pin 89 isv withheld from openings 81. Following'each movement of conveyor 33, cam |08 serves to permit downward movement ofvrod |09 and thus gravity movement of rod 94 Yand weight 95 against Y bell crank 90. In the event a container 34 is car# ried by conveyor 33 beneath nozzle I3, movement of pin 88 through openings 81 is resistedby cover portion 82 between guide members 83'and 84 and thus movement of flange |011 Vintermediate pawl 89 and ratchet wheel 10 is prevented.` This being the case, valve `21 is brought into operation and filling of the container :34 is completed. However, should'contairieru fail of carriage beneath nozzle I3 it is seen that passage of pin 88 through openings 81 will be permitted and that gravity movement of rod 94 will continue to the extreme of its downwardmostposition, As hereinbefore described, this latter movement of rod 94 will cause flange |01 to be moved intermef diate pawl 69 and ratchet wheel 10 and thus it will be seen thalt operationof ratchet wheel 10 and valves 21 for vented.
